Affidavits say law enforcement officers discovered the marijuana growing operation Tuesday at the Big Muddy National Fish and Wildlife Refuge in Howard County. Vazguez and Reyes were arrested at the site, and are in federal custody.

The affidavit says the operation encompassed about five acres and included five tents where marijuana was hung, dried, packaged and processed for delivery. Authorities said the plants were 5 to 6 feet tall.
